- To all whom it may concern:

Be it known that I, ANGUS A. MCKENZIE, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in a Folding Supporting-Frame for Portable Hand-Vises, of which thefollowing is a specification.

My invention relates to improvements in portable hand vises, and the object of the same is to provide a folding supporting frame which is simple in constructionand which. permits the folding of parts thereof for rendering the device compact when the sameis not in use or whilethe same is being carried about .inthe workmans kit or tool-chest. i i 'Another object is. to provide .a folding supporting frame for portable hand ises which, is designed to afford excellent gripup into Working. position by the clamping of the folding standardsinto the supporting j positions. Another object is to, provide a skeleton ing standards, whichmay be readilv set into working position for; rigidly supporting the claims.

frame of the vise when the same is to be used, and iwhich otherwisemay be folded occupying the-least space possible and ofi'ering a mostf 'convenient and serviceable-portable vise which'possesses all the good'w'orking qualities of the best known Vises.

p Still another object is to provide a folding supporting frame forportable Vises which normally may be folded into a compact space and otherwise may be-teinporarily or"per inanently set up into Working order by the unfolding of. pivoted standards and securely clamping the same into the supporting' position ;-the vise consisting'of a; rigid skeleton frame member having one fixed .j aw andone movable co-acting jaw,-wl1ich is actuated bythe turningof a crank, provided IE-0711131161 purpose, and'the said pivoted standards which arev pivotally' secured .to said skeleton frame memberfor supporting the same in the working position of the'vise.

To these as wellas other ends, my, inven-' tion consists 1n the novel features of -con-- struction, combination I and arrangement of parts set forth in the following specification,

and particularly pointed out in the subjoined of the vise, showing the same set in working position with the jawsaholding and grip- Speeification of Letters Patent. Patented Aug; 31, 1915. I I,

Fig. 8, is a'plan view corresponding to Fig. 1, which shows the standards folded .in the non-working position. Fig. 9, is a section taken on: line 99 in Fig. 8, looking in the direction of the arrows,

Likenumerals refer to like parts throughout the several views of the drawings.

The numeral 1 is a frame member provided with the sides 2 and 3, the stationary- ]aw 4c, the stop-lugs 5, and the. pivotingvbosses 6.. The jaws is'provided with the lbearing-bossal', and the opposite end' of the frameli's provided with the bearingboss 7 which form tlie'bearings for the feed or operating-screw 9." 10'is the movable jaw member which isprovidedwith the upperguide-fianges 11, the lowerguide-flanges 12,

and thetapped-hole '13, in which thefeedscrew 9'operates,the latterbeing held in operating position by the collar 14 which is pinned thereto for holding the in the operating position.

Fixed to turn with the end be secured tothe feed s crewinlany suitable manner, as, for example, by thepn 17. The

screwsj 19 and the clamping-studs 20, which studs 20 are provided with the winged-nuts .21, by meansof which the standards 18 may be secured into the required positions; The

of the feedscrew 9 is the operating-crank 16 whiehmay c I clipper: ends'22 of the folding-standards 18 are provided with the stop-lugs 23 which butt against the sides of the stops 50f the frame 1, when set in the working position, as shown in Figs. 1,2 and 5. The lower ends of the standards 18 are provided with the supporting-flanges 2 1 which arepreferably provided with the holes 21 for permanently securing the vise to the work-bench, et cetera,,when sodesired The flanges 2 1 may be provided with downwardly-projecting loops 25 for forming a shoulder to allow a purchase against the work-bench, as shown in Fig. 5. I I

The inner ends of thesides 2 and 3, toward the crank-end of the frame 1, are provided with the recesses 26 to permit the insertion of the movable jaw member within the frame member, so that the lower-guideflanges 12 may engage with the under sides of the frame guides 2 and 3 as shown in Figs. 1 and 2.

Having thus described the parts of my invention in detail, the mode of operation is asfollows. The various parts of the device may be assembled in the following manner: The movable-jaw member 10 may be engaged with the frame member by inserting the guides 12 within the recesses 26, provided at the crank-end of the frame, which permits the aw member to be lowered into position where the same maybe set on to th'eguide-runs 2' and 3 of the frame member. The operating-screw 9 may then be inserted from the crank-end'side through the bearing 8, when the collar 14 may be set over the same, and thereafter the operating-screw 9 may be screwed into the tapped-hole 13, provided in the movable-j aw member 10 for the purpose. The leading end of the operating-screw 9 may then be set in the bearing 7 provided on the stationary-jaw-end of the frame member. Upon thus setting the screw into its bearings, the collar 14 is then pinned into position" with the operating screw which preventsythe samefrom backing out through the bearing on the crank-endof the frame 'member. The operating-crank 16 maybe pinned, or otherwise attached, to the operating-screw in any suitable manner.

The standards may then be secured with the pivot-studs 19 and 20 to both ends of the frame member 1, as shown inthe drawings. The studs 20 are provided with the wingednuts 21, by means of which the standards 18 are rigidly secured to the frame member in the working or non-working positions, corresponding to Figs. 2 and 3, respectively of the drawings. It may be observedthat thestandards 18, when set into the unfolded position which is the working position, are allowed to butt up against the sides of the fstop-lugs 5, as shown in Fig. 2, and whenin the folded position which is the non-working position, are allowed tobutt up against the bottoms of the stop-lugs 5, as shown in Fig. I

positive gripping means between the two jaws for holding articles or material between them, and affording a wide range of action for operating on various widths of articles or materials.

It may thus be observed that the vise, as I have shown it, provides a very simple and effective device which may be used by workmen of various trades, permitting them to equip their kits or tool-chests with a compact form of portable vise, which consumes the least amount of spacewithout burdening the same with any excessive weight, and at the same time provides them with an absolutely positive and efficient form of vise which may be readily set into working position, and which may be positively relied upon for best service. j 7

It" may also be observed that the operating-screw may be threaded with a fine or coarse thread, according to the grade of work the vise is to be used in,thusaffording a vise which may be constructed to suit the conditions of the special lines of work required in the various trades." WVhile the preferred embodiments of the invention have been described in detail, it will be understood that I do notwish to be limited to the particular construction set forth, since various changes in the form, ma terial, proportion and arrangement of parts, and in the details of construction maybe resorted to without departing from the spirit any of the advantages contained in the same,

heretofore described and defined in the subjoined claims.

What I claim is 1, A folding supporting frame forvises, consisting of a rectangular frame member provided with an upwardly projecting end for forming the stationary jaw of the vise, end-bearings forsupporting the operating screw of the vise,and stop-lugs projecting outwardly from the sides of said frame member and positioned near the ends of'the same; a pair of foldable supportingstandards swingingly secured to said frame member near the ends of the same, provided with limiting-lugs at their secured ends for engaging with said stop-lugswhen set in the open position, and adapted to fold and close with said frame member; and locking members, securing said foldable supporting standards with said frame member and adapted to lock the former into the open or closed position with the latter. 7

2. A folding supporting frame for Vises, consisting of a rectangular skeleton frame member having the two longitudinal sides of the same adapted to form the runs for the movable jaw of the vise, one of the ends of the same projecting upwardly for forming the stationary jaw of the vise, both ends of the same supplied with longitudinal bearings for supportingthe operating screw of the vise and each side of the same provided with outwardly projecting stop-lugs near the ends of the same; a pair of transverse supporting standards swingingly, secured to the sides of said frame member at the ends of the same, adapted to fold and close with said frame member and provided with lim iting-lugs at their secured ends for engaging with said stop-lugs when set in the open position with the frame member, and supporting flanges on the free ends of the same provided with apertures for anchoring purposes; and pivoting members provided 5 with clamping means for swingingly engaging said standards with said frame mem ber and adapted to lock the former in the open or closed position with'the latter.
